JOHN WATT, OF SAOCARAPPA, MAINE, ASSIGNOR TO WOODBURY K. DANA, OF SAMEPLACE.

SLASHER.

SPECIFICATION forming part of Letters Patent No. 404,939, dated June 11,1889. Application filed March 27, 1889. Serial No. 305,037- (No model.)

To all whom, it may concern:

Be it known that I, JOHN WATT, of Saccarappa, in the town of Westbrook,county of Cumberland, and State of Maine, formerly a subject of theQueen of Great Britain, but having declared my intention to become acitizen of the United States in accordance with the Revised Statutes ofthe United States in that case made and provided, have invented a newand useful Improvement in Slashers, of which the following is aspecification, reference being had to the accompanying drawings, inwhich 1 Figure 1 is a plan, and Fig. 2 a side elevation, of a portion ofa slasher or sizing-machine embodying my invention, 3 is a side view,partly in section, on line 3 3 of Fig. 2.

My invention is an attachment for driving a cylinder of a slasher orsizing-machine, and thereby relieving the strain on the yarn; and itconsists in the combination of a cylinder of the slasher with its sideshaft with a jackshaft, belt, and tension device.

The parts not lettered in the drawings are well known and will bereadily understood by all skilled in the art, these being old and wellknown in slashers now in use.

In the drawings, A is a cylinder, which is provided with a gear a, whichmeshes with a pinion .a on jack-shaft a Jack-shaft a is provided with apulley a from which a belt a runs to a pulley a on the side shaft a ofthe machine. The tension of belt a is readily regulated by any suitabletension devicefor example, by a roll 1, mounted in a swinging arm 2,which is fulcrumed to the frame of the machine and moved to press theroll 1 against belt a, as required, by means of a screw 3 and nut 4, thescrew in this case being fast tothe arm 2 and extending through a partof the frame to receive the nut.

It is necessary in machines of this class that a uniform tension on theyarn be preserved, and consequently the belt which connects the sideshaft with the j ack-shaft is provided with a tension device, byadjustment of which the tension of the belt is kept uniform.

' For convenience the gear a is made in sections, so that it may bereadily secured to the cylinder A.

By driving the cylinder from the side shaft the strain on the yarn isreduced, the operation of the machine substantially improved, and thedanger of injuring the yarn minimized.

What I claim is In a slasher, the combination of cylinderA and sideshaft a with gear a, pinion a, jackshaft (1 belt a, side shaft of, and adevice for regulating the tension of the beltoirunning from a pulley aon jack-shaft a to a pulley a on side shaft a*, substantially as and forthe purpose set forth.

JOHN WATT.
